Parameters
vpn-instance vpn-instance-name: Specifies the VPN to which the symmetric-passive peer belongs, where
vpn-instance-name is a case-sensitive string of 1 to 31 characters. If the symmetric-passive peer is on the
public network, do not specify this option.
peer-name: Host name of the symmetric-passive peer, which is a string of 1 to 20 characters.
authentication-keyid keyid: Specifies the key ID to be used for sending NTP messages to the peer, where
keyid ranges from 1 to 4294967295.
priority: Specifies the peer designated by ip-address or peer-name as the first choice under the same
condition.
source-interface interface-type interface-number: Specifies the source interface for NTP messages. In an
NTP message the local device sends to its peer, the source IP address is the primary IP address of this
interface. interface-type interface-number represents the interface type and number.
version number: Specifies the NTP version, where number ranges from 1 to 3 and defaults to 3.
Description
Use ntp-service unicast-peer to designate a symmetric-passive peer for the device.
Use undo ntp-service unicast-peer to remove the symmetric-passive peer designated for the device.
By default, no symmetric-passive peer is designated for the device.
To synchronize the PE to a PE or CE in a VPN, provide vpn-instance vpn-instance-name in the command.
If you include vpn-instance vpn-instance-name in the undo ntp-service unicast-peer command, the
command removes the symmetric-passive peer with the IP address of ip-address in the specified VPN. If
you do not include vpn-instance vpn-instance-name in this command, the command removes the
symmetric-passive peer with the IP address of ip-address in the public network.
Examples
# Designate the device with the IP address of 10.1.1.1 as the symmetric-passive peer of the local device,
configure the local device to run NTP version 3, and specify the source interface of NTP messages as
GigabitEthernet 0/1.
